HEEL-BUILDING MACHINE.

Application filed March 8, 1918.

To all whom it may concern:

Be it known that 1, CHARLES O. RYBERG, a citizen of the United States,residing at Brockton, in the county of Plymouth and State ofMassachusetts, have invented new and useful Improvements inHeel-Building Machines, of which the following is a specification.

This invention relates to machines for cutting heel lifts from blanks ofsuitable material and forcing the lifts progressively into and throughan, elongated guide or chute, from the lower end of hich the lifts drop,the lifts being preferably cemented together in groups during thebuilding operation, each group constituting a heel body which dropsindependently from the chute, the elongation of the chute being suchthat the cement has time to dry or harden while the heel bodie arepassing through the chute.

The invention is embodied in the several improvements which I will nowproceed to describe and claim.

Of the accompanying drawings forming a part of this specification,

The same reference characters indicate the same parts in all of thefigures.

I will for the present exclude from the description the constructionshown by Fig. 14.

12 represents the fixed bed of the machine supported by legs 13, (Fig.1). To the bed is attached by screws 14, (Figs. 3 and 4), a die blockrest including a fixed member 15, formed as a frame having a relativelylarge heel-shaped socket communicating with an opening 16, (Fig. 4), inthe bed, the wall of said socket being preferably tapered, and a taperedlining or bushing 17, removably seated on the socket wall and formingthe rest opening, the size of which may be varied, by using differentbushings interchangeably. Two vertical rods 18, movable vertically bymeans hereinafter described in guide orifices in the bed 12, areprovided at their upper ends with bearings 19 in which are journaled twoalined horizontal shaft or trunnion members 20, 20, the inner ends ofwhich are secured, as by set screws 21, 22, to a heel-shaped die block28.

To opposite sides of the block 23 are attached tw heel-shaped cuttingdies 24, facing in opposite directions, each die having slotted ears(Fig. 3), attached by screws 26 to the die block. The under side of thedie block is seated loosely on the rest formed by the member 15 andbushing 17, the downwardly facing lower die projecting into and throughthe opening in the rest. The upwardly facing upper die is thereforerigidly supported by the die block and adapted to cooperate with thereciprocating platen hereinafter described, in cutting heel-lifts frommaterial placed on the upper die, each lift being forced by the plateninto the upper die. Z (Fig. 4), represents an upwardly facing heel-liftwhich has been out and forced into the upper die. After enough lifts fora heel body have been thus deposited in the upper die, the die block isfirst raised to remove the lower die from the rest opening, as shown bydotted lines in Fig. 5, and a half rotation is then manually imparted tothe die block to invert the group of lifts, the die block being thenlowered and again seated on the rest, to permit the ejection of thegroup of lifts into a vertical elongated lift guide or chute, locatedbelow the die block and adapted to receive and guide a plurality ofgroups which are ejected into the upper end of the chute, and are forceddownwardly therein. Said chute may be composed of sections -2727 and 28,(Figs. 4 and 16), which may be rendered adjustable relatively to eachother, and rigidly supported by any suitable means. As shown by Fig. at,the adjusting and supporting means may include screws 29, 29*, journaledto rotate without endwise movement on the frame, and suitableconnections between said screws and the chute sections includingslidable tapped members 29 29 engaged with the screws and with the chutesections. The lifts of each group are cemented together and constitute aheel body. The top and bottom surfaces of each body are preferably leftnon-adhesive, so that each heel body, on reaching the lower end of thechute, which is open, drops into a receptacle under the chute.

The means here shown for manually raising and lowering the heel blockand dies in-,

cludes a rock-shaft 30 (Figs. 1 and 4t), rocker arms 31 attached to saidrock-shaft and pivoted at 32 to the lower ends of the rods 18, and anarm 33 attached to one end of the rock-shaft and provided with a handie34. When the operator moves the arm 38 in the direction of the arrow,(Fig. 1), the rods 18 are raised and act through the members 20 to raisethe die block and dies.

- with diametrically opposite depressions 38,

(Fig. 6) cooperating with the detent to yieldingly retain the die blockafter a half rotation.

The depth of each die is such that it is adapted to receive a group oflifts forming one heel body, the upper the remaining in a fixed positionuntil it has received the group of lifts, as shown by Fig. 17. The liftsact through a plunger 39, (Figs. 4: and

12), to eject from the lower die into the chute a previously assembledgroup of lifts. Said plunger is movable in a guide opening in the dieblock, and is provided at its opposite ends with oppositely facingheelshaped heads 40, having a sliding fit in the dies. lVhen one die hasreceived a group of lifts, the entire group previously inserted in theother die is ejected therefrom into the chute, so that the die block anddies may be raised preparatory to a partial rotation, which inverts thlast assembled group of lifts and prepares them for ejectment into thechute.

The heads 40 are spaced apart to permit the insertion of a plurality orgroup of lifts in the upper die, so that said lifts may be united in theupper die by glue applied, as above described, to surfaces of saidlifts, the plunger being displaceable by a group of lifts inserted andunited in the upper die to eject a group of united lifts from the lowerdie.

To inform the operator when a group of lifts is completed in the upperdie, I provide at each side of the die block an indicator which is afinger 42, (Figs. 3, i and 7), having an enlarged shank 4,3 movable in arecess a l in the plunger 39, and guided by a steady pin 47. The finger&2 at the upper side of the die block, is normally held by a spring {15above a slot 426 in the die block, and projects through an opening inthe die, so that it' may be seen by the operator. /V hen a group oflifts has been completed inthe die, the finger is pressed into the slot46, its position indicatmg that the group has been completed. When thedie block is inverted, the finger 42, now flush with the lower surfaceof the die block, bears on the upper surface of the rest bushing 17,until the die block is again inverted, the spring 4:5 then raising thefinger from the slot in the die block.

The lifts may be solid and cut from a strip Z of leather-board, or othersuitable material, or they may be composed of pieces Z cut from wastescraps of material such as leather. In practice, I prefer to use two ormore solid lifts and one or more pieced lifts for each heel body. Ineither case, the material is deposited on the upper die and cut by thecooperation with said die of a reciprocating platen.

I provide means shown by Figs. 10 and 15, for guiding a strip Z to theupper die, and at the same time, coating the under side of the stripwith glue, said means including a glue reservoir 50, a corrugatedglue-applying roll 51 partly immersed in the glue, and spring fingers 50adapted to hold the strip against the upper portion of the roll, thearrangement being such that a strip Z may be drawn by the Operator overthe roll 51 and upon the upper die 2 which 4 S9 with the slide 74.

is located adjacent to one end of the reservoir 50, as shown by Fig. 15.In making pieced lifts the operator assembles the pieces Z on the upperdie, after coating said pieces with glue by means of a hand-operatedbrush. As shown by Figs. 10 and 15, the reservoir 50 is provided with aglue conduit 54: communicating with a vertical well 55 in which thebrush may be inserted to receive glue. A brush rest 56 formed by aflange surrounding the well 55, is provided to support the brush when itis not in use. To enable the operator to form straight abutting edges onthe pieces Z I provide an edging mechanism shown by Figs. 1 and 11, andincluding a frame having end uprights 58 attached to a bracket 59 boltedto the frame of the machine, and shearing cutters 60 and 61, the cutter60 being fiXed and the cutter 61 being vertically reciprocated byeccentrics 62 fixed to a horizontal shaft 63, straps 6% on theeccentrics, and a carrier 65 for the cutter 61, pivoted at 66 to thestraps, the carrier being engaged with suitable fixed vertical guides inthe uprights 58. The shaft 63 may be continuously driven by asprocket-chain 67 engaged with a sprocketwheel 68 secured to a pulley 79which is continuously driven by a belt, and a sprocket-wheel 69 on theshaft 63. The edging apparatus is conveniently located adjacent to theupper die and above a fixed tray 72 adapted to contain a supply ofleather scraps. The platen which cooperates with the upper die, includesa ositively reciprocated head 73, (Figs. 8 an 9), attached to a slide 74which is reciprocated in fixed vertical guides 75 by power suitablycommunicated from a shaft 70, which is driven by the pulley 79, througha clutch (not shown), one member of which is carried by the pulley 79,and the other by a pulley 78 attached to the shaft 70. Means (not shown)may be provided for impart ing oscillating motion from the shaft 70 to arocker-arm 88, which is connected by a link Means may also be providedfor automatically stopping the motion of the platen head after it hasmade one downward and one upward movement, the platen head remaining atrest in a raised position until it is again started by an act of theoperator.

Connecting mechanisms or automatic stop motions organized to be operatedas above indicated, are well known, and therefore do not require fullillustration and description, it being sufficient to say that themembers of the clutch connecting the pulleys 79 and 78 may beinterengaged by the depression of a foot lever 80, or a hand lever 81,and separated by automatic means including a vertical rod or strut 82,secured at its lower end to the platen head 73, and acting at the end ofthe upward movement of the platen head through connections with the footlever, said connections including a lever 83, a rod 84, a lever 85, anda rod 86, (Fig. 2).

It will now be understood that when the rises, it remains at rest untilthe hand lever or the foot lever is again depressed.

While my invention does not relate to the platen starting and stoppingmechanism, any suitable form of which may be employed, it includes asafety device on the platen adapted to guard against injury to theoperators digits, in case they project, as indicated by Fig. 9, betweenthe lift material and the platen when the latter is descending.

Referring to Figs. 8 and 9, 90 represents a loose platen head providedwith a brass facing 90*, adapted to contact with the die without injurythereto, and with an upstanding flange 91 surrounding the positivelyreciprocated head 73, said flange having hooked ears 92 engaging andadapted to rest loosely on a shoulder 93 on the head 73. The loose head90 has a stem 95 and a steady pin 96, fitted to slide in verticalorifices in the head 73. The weight of the loose head is suflicient tocause it to normally assume the position shown by Fig. 8, the ears 92resting on the shoulder 93. The loose head is therefore adapted to beseated on the lift material during the descent of the platen, the weightof the loose head being suflicient to hold the lift material on the diewhile the head 73 is completing its downward movement, said headabutting against the loose head, so that the latter is positivelypressed against the lift material.

In case, however, the operator carelessly allows his forefinger andthumb to remain in the path of the descending platen, the loose headyields, as shown by Fig. 9, and imparts a warning pressure before it ispositively advanced by the head '73, so that the operator has time towithdraw his finger and thumb, and thus avoid serious injury.

96 (Fig. 13), represents a heel-shaped fill ing piece, adapted to beapplied to the plunger 39, as indicated by dotted lines in Fig. 12, incase the operator desires to build a relatively thin heel body, or onecomposed of a relatively small number of lifts. Two of these fillingpieces may be employed, one for each head 40.

Referring to Fig. 14, it will be seen that the plunger 39 is omitted.the die block 23 having an enlarged heel-shaped opening conforming tothe internal surfaces of tin dies 24, so that lifts cut by the upper diepass through said die, through the die block,

and through the lower die. In this modification, the die block isinverted only when it becomes desirable, on account of wear of thecutting edge of the upper die, to bring the lower die into cuttingposition.

At the commencement of the operation, the operator deposits liftmaterial on the upper die. In case the lift material is a strip Z theoperator draws the strip across the glue-applying roll 51, thus coatingits under side with glue, so that the cut lift is caused to adhere to alift previously inserted in the die. A pieced lift may be formed byassembling a. suitable number of pieces on the die, each piece beingfirst provided with a straight edge by inserting a portion of it betweenthe cutters 60 and 61. The operator assembles a suitable number ofpieces to cover the upper die, and at the same time abuts the straightedges, formed as last described, closely together. The pieces may becoated with adhesive by the use of a brush dipped in the well 55. Whenthe plunger 39 is employed, the lift-forming operation is repeated untila group of lifts is deposited in the upper die, and the correspondinggroup of lifts is ejected from the lower die, as indicated by Fig. 17after which the operator raises and inverts the die block, thuspreparing the group of lifts which were inserted in the upper die forejection into the chute.

As shown by Figs. 10 and 15, the reservoir 50 is provided with guides50*, arranged to bear on the edges of the strip Z and guide the strip tothe adjacent cutting die. The strip is pressed against the roll 51 byspring fingers 50 I claim:
